Specification of Letters Patent.

Patented July 15, 1913.

Application filed January 19, 1910. Serial No. 538,877.

To all whom it may concern Be it known that we, WVILLIAM E. HOLDER and RICHARD SAMPSON, both of the city of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in Hot Plates for Stoves, of which the following is a full, clear, and exact description.

This invention relates to hot plates for stoves and the main object of the'invention is to provide a simple, inexpensive and efficient plate or stand which may be used over a single gas jet to heat either one or a plurality of cooking utensils at the same time.

A further object is to provide a device by means of which the heat from the gas flame is deflected toward the points where it is most needed to thus obtain the best results from a minimum amount of fuel.

The invention consists of a plate or stand having a peripheral depending flange upon which it rests, said plate being provided with two or more series of apertures through which the heat rises to any utensil placed above same upon the stand. A thickened removable lid is fitted centrally into the plate and is convex or dome shaped on its under side to deflect the heat radially outward toward the apertures. Between the sets of apertures the flange of the plate is curved inwardly to deflect the heat toward the apertures through which it is designed to pass.

In the drawings, Figure 1 is a plan view of the plate. Fig. 2 is an inverted plan view of the plate. Fig. 3 is a vertical sectional view on the line 55 of Fig. 1.

In the above defined figures 6 designates a plurality of similar segments forming an approximately circular plate, the segments being secured together by means of flanges 7 and connecting bolts 8. The sections are so formed that when secured together the completed plate will have a plurality of substantially semicircular notches or depressions 9 in the outer edge thereof. The entire plate is supported on a peripheral depending flange 10 which follows the contour of the plate, as clearly shown in Fig. 2. Each section of the plate is provided, between the notches 9, with a series of apertures 11 preferably arranged in radial rows with the apertures of one row staggered with respect to the apertures of adjacent rows, as shown in the drawings. A centrally located circular lid 12 is provided which rests on a suitable supporting flange 13 to which it may be attached by bolts 14:. It will be understood that when the plate is in operation the use of the bolts is optional as the lid 12 will remain in position similarly to an ordinary stove lid. The top 15 of the lid is flat but the bottom 16 is convex or dome shaped for the purpose of deflecting the flame and heat toward the periphery of the plate. A suitable depression 17 containing a cross bar 18 may be provided in the center of the lid to cooperate with any ordinary stove lid lifter in the usual manner. The under surface of the plate is provided with a plurality of concentric flanges or ridges 19 which project a short distance below the plate and serve to break the outrush of the flame and to direct it upwardly through the apertures 11. The plate and lid are both provided with a plurality of small raised bosses 20 on the upper side thereof adapted to support a utensil placed on the plate a suflicient dis tance thereabove to allow the escape of flame and heat rising through the apertures 11. It will be obvious that the form of the depressions 9 may be changed from semicircular to any other suitable shape without altering the purpose thereof or detracting from the efliciency of the device.

When in use the plate is placed over a gas jet or single burner of a gas or oil stove.

-The flame and heat rise into contact with the convex bottom of the lid and are deflected radially thereby to pass up through theapertures 11 in the top of the plate. The flange surrounding the notches or depressions 9 also throws the heat toward the apertures 11 so that the heat is concentrated as it rises through the said apertures.

Having thus described our invention, what we claim is 1. A device of the class described comprising a plate having a plurality of sets of radial apertures arranged in concentric rows, a plurality of concentric depending flanges on the lower surface of said plate positioned to intersect the apertures of adjacent rows, and a comparatively deep supporting flange for said plate adapted to prevent the escape of heat at the periphery thereof.

2. A device of the class described comprising a plate having a plurality of sets of radial apertures arranged in concentric rows, a plurality of concentric depending of bosses on the upper surface of the plate flanges on the lower surface of said plate to support utensils thereabove.
